In DCF, a project, company, or asset is valued based on its cash flows. [1] Hence, they are dealt with only indirectly, via their cash flows and ‘финансовые средства’ cannot be translated directly as assets, resources or investments.

On the other hand, (1) loans are treated as ‘Cash Flow From Financing Activities’ [2] in cash flow analysis, and (2) ‘единовременные финансовые средства’ are defined in the context as ‘вид’ of incomes and expenses [3]

Hence the use of the generic name for loans/credits, etc. in the suggested translation.

[1] ‘All future cash flows are estimated and discounted by using cost of capital to give their present values (PVs)’ -- https://en.wikipedia.org/wiki/Discounted_cash_flow

[3] доходы и расходы в виде денежных потоков ... и единовременных финансовых средств
